Thickness of the oxidation layer 70 a can depend on time and temperature the interconnection 60 being exposed to the air (or oxygen).

The relatively great contact resistance may adversely affect performance of the semiconductor device package 1 e.

A cleaning operation, for example but is not limited to a wet etching technique, can be performed to remove the oxidation layer. However, in order to remove most or the entire oxidation layer, the cleaning operation may last for a relatively great period of time, which may inevitably damage the insulation material or dielectric material (e.g. the encapsulant 60) to form an undercut 60 v or a void 60 v. The void 60 v may adversely affect performance of the semiconductor device package 1 e.
